Water quality measurements made easy The only simultaneous absorbance and fluorescence system for water quality analysis! The new Aqualog is the only instrument to simultaneously measure both absorbance spectra and fluorescence Excitation-Emission Matrices. EEMs are acquired up to 100 times faster than with other instruments. Dedicated software automates traceable Quinine Sulfate Unit calibration and correction of inner-filter effects and Rayleigh and Raman scattering lines, enabling rapid export to multivariate modeling programs including our partner, Solo, by Eigenvector Research, Inc....
